Introduction
Marine linear actuators are electric actuators designed to operate in harsh marine environments. They are waterproof, corrosion-resistant, and often 12V for easy integration with boats, yachts, and other marine applications.
What is an Electric Linear Actuator?
An electric linear actuator converts the rotational motion of a motor into linear motion through a mechanical transmission mechanism. In marine applications, this is often called a marine electric actuator, which is engineered to resist seawater corrosion, high humidity, and the challenges of harsh environments. Understanding their function helps you select the right actuator for your project.
Applications of Marine Linear Actuators
Marine Linear Actuator 12V
12V marine actuators are ideal for controlling hatches, steering mechanisms, rudders, or lifting small loads on boats. Waterproof 12V marine linear actuators are widely used on boats and yachts for reliable motion control while keeping power consumption low.
Underwater & Waterproof Linear Actuators
Some actuators are fully submersible, making them suitable for underwater marine applications. Actuators with IP67, IP68, or IP69K ratings provide reliable protection against dust and water ingress.
Tips for Choosing Marine Actuators
When choosing an actuator, consider factors such as load, speed, environment, and IP rating. Choose Bestop, a manufacturer offering robust design, warranty, marine-grade certification, and ISO 9001 certification, to ensure long-lasting performance. Bestop also provides custom marine linear actuators, tailored to specific requirements for load, stroke, and speed, ensuring the perfect fit for your marine project.
Key Factors to Consider When Choosing a Marine Linear Actuator
- Load Capacity – The maximum force the actuator can handle without compromising performance.
- Stroke Length – The total distance the actuator rod can extend or retract.
- Speed and Duty Cycle – How fast the actuator operates and how long it can run without overheating.
- IP Rating – Indicates protection against water and dust ingress, essential for marine environments.
- Material Corrosion Resistance – The actuator’s ability to withstand corrosion from saltwater and humid conditions.
- Voltage Requirements – Ensures compatibility with the vessel’s power supply.
Ingress Protection (IP Ratings) Explained
- IP67 – Protected from temporary immersion in water up to 1 m for 30 minutes.
- IP68 – Protected for continuous immersion in water, with depth and duration specified by the manufacturer.
- IP69K – Dust tight and protected against high-pressure, high-temperature water jets.
IP ratings indicate the level of protection against dust and water ingress, with higher ratings offering better resistance in challenging environments. IP ratings are defined by the IEC 60529 standard from the International Electrotechnical Commission (IEC), helping you choose the right marine linear actuator for your boat, yacht, or underwater application.
Setup & Wiring Diagrams
Marine linear actuators typically come with wiring diagrams and detailed instructions. Correct wiring is essential for long actuator life and safe operation. Always follow the manufacturer’s guidelines. The marine linear actuator wiring diagram below shows a typical setup for reference.
Frequently Asked Questions (FAQ)
1. Can a marine linear actuator work underwater?
Yes, some actuators are fully submersible and rated IP68 or IP69K. Always check the manufacturer’s specifications before underwater use.
2. What voltage do marine linear actuators use?
Most marine actuators operate at 12V or 24V DC, which are standard for boats and yachts.
3. How do I choose the right IP rating?
-
IP67: Short-term immersion, occasional splashes
-
IP68: Continuous immersion in water
-
IP69K: High-pressure, high-temperature water jets
Consider your operating environment and exposure to water or dust.
4. How long can a marine actuator run continuously?
It depends on the duty cycle specified by the manufacturer. Exceeding the duty cycle can cause overheating and reduce lifespan.
5. Can I install a marine linear actuator myself?
Yes, if you follow the wiring diagrams and manufacturer instructions carefully. For complex applications, professional installation is recommended.
